routers bandwidth is not being measured correctly

I`ve downloaded the trial version to compare with other products and I`m having a problem with OPSView because we can`t set up manually the bandwidth from a router and OPSView is get the wrong one.

I`ve defined the threshold to 50% as warning and 70% as critical for my real bandwith and I`m having percentages of 653% of threshold. Then I`ve verified and queried the router with OPSView and found the return result from OPSview as 1Mbit but my router as 8Mbit so that`s the problem.

Is there any way to set manually the Bandwidth for a device?

Apart of that on the pro version still the problem with the program end and program restart as in core one.
